Application filed March 30, 1904:. Serial No, 200,661. (No modelfl "171mm 7'15 "1/ concern: and particularly pointed out in the following Be it known that I, GEORGE OTIS DRAPER, claims.

a citizen of the United States, and a resident Figure 1 in side elevation and partial secof .Hopedale, county of l/vorcester, State of tion represents a suflicient portion of a yarn- 5 Massachusetts, have invented an Improvespinning apparatus to be understood with one ment in Ring-Spinning Apparatus, of which form of myinvention embodied therein.

The novel features of my invention will be As will be manifest from an inspection of fully described in the subjoined specification Fig. 1, the upper face of theannular projection 7 forms a fixed rest for and upon which the outer end 10 of the traveler slides, vertically supporting the traveler exterior to the ring and distributing the wear. The traveler is maintained in a more nearly upright position, and by supporting its outer end throughout its circular path of movement the traveler cannot rock or move unsteadily owing to variations in the yarn pull, and as the traveler is thus in a measure balanced and. its movement .rendered more uniform and the wear more equally distributed over both ends of the traveler the latter will last longer and can be run with a higher spindle speed.

In the modification shown in Figs. 3 and 4: the web 12 of the ring is reduced in height and each of the outer flanges 13 is somewhat thickened, so that the lower one of said flanges serves as a rest, the outer end of the traveler being supported by the upper flat face 14: of the rest-forming flange. This ring can be reversed, as will be obvious, the uppermost outer flange l3 and the opposite inner flange 15 constituting the traveler-race, as shown in Fig. b. ith the modified ring shown the form of ring-holder illustrated in Fig. 1 could not be employed, as the holding-lips would interfere with the movement of the traveler; but some other suitable holding means could be employed as, for instance, a ring 16, secured to the ring-rail and having an upturned lip 17 (see dotted lines, Fig. to fit within the lower inner flange 15.

Having fully described my invention, what I. claim as new, and desire to secure by Letters Patent, is-

1. A reversible double-flanged spinningring, each set of inner and outer flanges forming a traveler-race, and an outwardly-extended, fixed annular projection between the upper and lower outer flanges, to form a rest for the outer end of the traveler when the latter cooperates with either race.

2. A reversible double-flanged spinningring and an external annular projection integral therewith and projecting laterally beyond the outer flanges of the ring, said projection forming a rest to support and steady the outer end of the traveler when the latter cooperates with the double flanges at either the top or bottom. of the ring.

3. In combination, a non-rotative reversible spinningring having oppositelyextended flanges at the top and bottom thereof, a flatfaced annular traveler-rest integral with the ring and located between the outer flanges thereof, and a traveler adapted to be supported at its outer end by the uppermost face of said rest when the traveler is in cooperation with either pair of the oppositely-extended flanges.

1. A non-rotative spinning-ring comprising a w eb and opposit-ely-extended annular flanges at both top and bottom of the web, and. an external projection on and integral with the web and symmetrically disposed with relation to the outer flanges thereof and extended laterally beyond the peripheries of said outer flanges.

5] A spinning-ring comprising a web and oppositely-extended annular flanges at top and bottom of the web, and an external projection on and integral with the web and symmetrically disposed with relation to the outer flanges thereof, the upper and lower faces of said projection being parallel to each other and extended laterally beyond the peripheries of the outer flanges, one or the other face being adapted to support the outer end of a traveler when cooperating with the oppositely-extended pair of flanges above the projection.

6. A reversible spinning-ring having inner and outer horizontal flanges forming a race for the traveler, a traveler cooperating therewith, a ring-holder to engage and retain the ring from rotation, and an annular lixed rest on and exterior to the ring and adapted to vertically support the outer end of and steady the traveler.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
